Which equation represents the line through (4, 5) and (0, 3)?

morpeh [17]

Answer:

I dont know what options you have but all these are possible answers

y - 5 = 1/2 ( x - 4 )

y - 3 = 1/2 x

y = 1/2 x + 3

Step-by-step explanation:

In order to find the equation you need a slope, so you find the slope of both points by using the slope equstion

y2 - y1 / x2 - x1

and you would get :

$\frac{1}{2}$

now you plug it into the point slope formula which is y - y = m ( x - x )

and you choose one of the two sets of points that they provided in the question but you'll get the same answer either way.

Antonio’s pizza charge $8.00 for a large pizza and $1.50 for each topping zine’s pizzeria charge $10.00 for a large pizza and $1

hichkok12 [17]

In this problem you would set these two equations equal to each other.
$8+ $1.50x = $10+ $1x
After this you would simplify the equation to isolate x (being the number of toppings you put on the pizzas)

$8+ 1.50x =$10+ 1x
-8 -8
----------------------------
$1.50x = $2 + $1x
-1x -1x
---------------------------
$.50x/.50 = $2/.50
_______________
x= 4 toppings and the pizzas would equal $14 total

Solve for x in the equation 2x^2+14x+17=-96

goblinko [34]

$2x^{2}+14x+17=-96 \newline
2x^{2}+14x+113=0 \newline
\Delta = b^{2}-4ac = 14^{2} - 4 \cdot 2 \cdot 113 = -708.$

Since $\Delta$ is negative $\Rightarrow x \notin \mathbb{R}.$
